3D LiDAR sensors

Anonymous and reliable people counting

Your Benefits

  • Anonymized people counting in public spaces
  • Read out of current utilization of space
  • Reliable identification of the direction of movement of people at entrances and exits
  • Reliable differentiation between humans and objects: Humans are detected and objects are not considered due to their contours.
  • Quick and easy commissioning


Anonymous and reliable people counting

The PeopleCounter is a solution developed by SICK which enables differentiation of people from objects over large detection areas. Based on the hardware of the MRS1000 3D LiDAR sensor, which generates measurement data in the form of a point cloud, the integrated SensorApp processes the data. With the PeopleCounter, people can be reliably identified using their contours. This means only people are counted, while objects are blanked out. The process runs without recording personal data, ensuring anonymized data processing.

At a glance
  • Exact measurement data output via telegrams and digital outputs
  • Intuitive user interface for representation and configuration of the application
  • Large aperture angle and four layers of the MRS1000
  • Shoulder-head-shoulder contour detection
  • Pre-programmed, application-specific app based on a 3D LiDAR sensor


SICK has the solution for quickly, easily and anonymously identifying the exact number of people in a space: the PeopleCounter, a combination of an MRS1000 3D LiDAR sensor and a SensorApp. The PeopleCounter makes it possible for 3D-LiDAR sensors to count of people using artificial intelligence. With its four scan planes, the direction of movement of people is identified and people are detected as such by the SensorApp thanks to the detection of head and shoulder contours. This makes it possible reliably differentiate people from objects.

PeopleCounter complete package: the MRS1000 3D LiDAR sensor generates the measurement data and the integrated SensorApp reliably identifies people using their contours.

PeopleCounter in use – people are reliably detected and accurately counted
The four scan planes of the MRS1000 scan the direction of movement of people
The detection of head and shoulder contours ensures reliable differentiation of people from objects

Anonymous people counting: identification and classification of people using their contour data without taking pictures or recording personal information

Thanks to the adjustment options of the SensorApp, the PeopleCounter can be applied in a wide range of areas: for example, operating entities of public as well as tourist facilities, restaurants and retail stores can profit from its use. In addition to monitoring the current number of people in a space, different app functions enable the collection of additional information, such as the time at which most of the people entered or exited the space or the time of day at which the most people were situated in a pre-defined area.

The PeopleCounter features many functions and delivers useful information for processing the collected data.

The PeopleCounter features a master-slave function. This allows for the use of more than 10 devices. It also enables the monitoring of several access points to a space and the monitoring of entry and exit areas of more than 10 m in width.
In real time, the MRS1000 detects the current number of people in the monitored area and evaluates the corresponding data. An additional computing unit is not necessary. Complete sets are available for quick commissioning.
The PeopleCounter outputs the collected data via measurement telegrams and digital outputs. The current space utilization can then be displayed directly on a monitor, or using a traffic light system as is sometimes used for regulating entry into businesses. The data is available for up to 30 days in the internal memory of the PeopleCounter.

Person detection with a counting accuracy of more than 98% – there is no risk of confusing people and objects such as shopping carts

SICK LifeTime Services

SICK’s services increase machine and plant productivity, enhance the safety of people all over the world, provide a solid foundation for a sustainable business operation, and protect investment goods. In addition to its usual consulting services, SICK provides direct on-site support during the conceptual design and commissioning phases as well as during operation.

The range of services not only covers aspects like maintenance and inspection, but also includes performance checks as well as upgrades and retrofits. Modular or customized service contracts extend the service life of plants and therefore increase their availability. If faults occur or limit values are exceeded, these are detected at all times by the corresponding sensors and systems.

Consulting and design Application-specific advice on the product, its integration and the application itself.
Commissioning and maintenance Application-optimized and sustainable ─ thanks to professional commissioning and maintenance by a trained SICK service technician.
Service contracts Extended warranty, SICK Remote Service, 24-hour helpdesk, maintenance, availability guarantees and other modular components can be individually combined on request.
